Watch Superman Appeared in this Alternate Scene from GRAVITY

I didn't know that the Man of Steel made an exclusive appearance in this alternate scene from the movie Gravity. Now I have to say that I have not seen the Gravity yet for some unknown reasons and most of my friends who have seen it are telling me to watch it as soon as possible. I think I am going to watch it in a couple of days. This post may be a little bit late as this video below was uploaded on YouTube on April 1.
